Review on Cipher X Ray Technique to Analyze and Implement Cryptographic Operation

Identifying a given binary program implements a specific cryptographic algorithm and finding out more information about thecryptographic code is an important problem. In this paper, we present several methods to identify cryptographic primitives within a given binary programin an automated way. CipherXRay is a novel binary analysis framework that can automatically identify and recover the cryptographic operations. CipherXRay able to pinpoint the boundaries between the multiple rounds of cryptographic operation. It can further identifies certain operation modes (e. g. , ECB, CBC, CFB) of the identified block cipher and tell whether the identified block cipher operation is encryption or decryption in certain cases. This results that current software implementations of cryptographic algorithms hardly achieve any secrecy if their execution can be monitored.
